Cannot Access All Directory Pages After Update

After the last update i canot access all directory pages, i can only get to page 2 and after that the rest of the pages will not load but will be stuck on page 2. If i start with page 4 or 3 the same thing happens, i cannot go to page 2 or 1. Was working perfectly before ad i have done nothing as far as installig a plugin. I tried on 3 other themes and the issue remains the same http://musicjehad.com/directory/
